During the period of the Chu-Han war, the world was in chaos, and many people died in this war, but there were also many heroes Haojie born here. For example, there is a person named Yang Xi.
He was originally a small soldier under Liu Bang's account, his professional ability was not outstanding, he did not kill many enemies, and there were not many military feats to brag about.

However, he was able to be crowned in the last battle, and history left a name. The reason why he was able to achieve this was because of one thigh!
This thigh is not someone else's, it is the Western Chu Overlord Xiang Yu's!
This has to start with the last battle between Liu Bang and Xiang Yu, the Battle of Gāi.
In October 202 BC, Liu Bang, Dou Bao, and Yingbu attacked Pengcheng, where Xiang Yu was located, with soldiers and horses. At that time, the situation was very unfavorable to Xiang Yu, and in desperation, Xiang Yu had to retreat to the southeast.
In November, Xiang Yu retreated to Xiaxia (present-day Lingbi, Anhui), camped on the spot, reorganized the soldiers and horses, and restored the strength of the troops, at this time the Chu army still had more than 100,000 soldiers.
In December, Liu Bang joined together several large armies such as Han Xin, Peng Yue, and Yingbu, and surrounded more than 100,000 Chu troops under the siege. Han Xin personally led 300,000 Han troops to attack the Chu army and beat the Chu army to a pulp. The Chu army was defeated, but there were still some remnants of strength.
One night, the Han army sang Chu songs in unison, and the morale of the Chu army collapsed. Xiang Yu saw that the general trend was gone, so he took advantage of the night to lead eight hundred cavalry to break through the heavy encirclement of the Han army and flee in a southerly direction.
It was not until dawn that the Han army learned that Xiang Yu had broken through and fled, and immediately sent five thousand elite cavalry to chase Xiang Yu. When Xiang Yu fled to Dongcheng (東城, in present-day Dingyuan, Anhui), he was pursued by the Han army, and only twenty-eight of his eight hundred cavalry remained.
Xiang Yu commanded these twenty-eight cavalrymen, charged with the 5,000 elites of the Han army, killed a bloody road again, and continued to flee south, fleeing to the edge of the Wujiang River (now Anhui and County).
At this time, Xiang Yu's heart was full of sorrow, and the brothers who had followed him out to break into the world were now only left with more than twenty people who were now accompanying him. He felt that he did not have the face to go back to see Jiangdong's father and elder, so he decided to fight with the Han army to the death.
Xiang Yu ordered all the cavalry to dismount and fight the Han army with weapons. Xiang Yu alone killed hundreds of Han troops. However, the number of helpless Han troops was too large, and Xiang Yu was invincible, and he was wounded in more than ten wounds.
Xiang Yu was exhausted by the time he killed, and he couldn't even hold his weapon steadily, so he could only try his best to stand and not let himself fall. The Han army surrounded him, but none of them dared to rush up and kill Xiang Yu.
At this time, Liu Bang, who was standing on the side, shouted loudly: "Who can kill Xiang Yu and seal the Marquis of Ten Thousand Households!" ”
A group of Han soldiers and soldiers listened, looked at each other, or rushed to Xiang Yu. At this moment, Xiang Yu suddenly saw an acquaintance among the Han soldiers, and Xiang Yu recognized him and said to him, "Boy, I have fulfilled you today!" Take my corpse and go get the reward!" ”
As soon as the words fell, Xiang Yu picked up the sword and killed himself.
When the Han army saw that Xiang Yu had committed suicide and died, they rushed up and snatched his body. In the process of looting, not only xiang Yu's body was divided into several pieces, but several Han soldiers killed each other. In the end, a small soldier was lucky enough to grab Xiang Yu's thigh and then deliver it to Liu Bang.
Liu Bang asked happily, "What is your name?" ”
"My name is Yang Xi!"
"Good!" Liu Bang promised a thousand gold and made Yang Xi the Marquis of Chiquan. The other soldiers who snatched Xiang Yu's corpse were also given the title of Marquis.
Since then, the Yang Xi family has become prominent.
Because the titles of the Han Dynasty were hereditary, Yang Xi's children and grandchildren were also marquises. When the title passed to his great-grandson Yang Chang, it changed.
Emperor Xuan of Han made Yang Chang the Marquis of Anping, and this Yang Chang had another identity, he was the son-in-law of Ma Qian of the Taishi Company. Yang Chang was a very capable person, and served in senior positions such as the Western Han Dynasty's chancellor and imperial chancellor. The Yang clan also started from his generation and slowly reached the peak.
Yang Xi's eighth grandson, named Yang Zhen(杨振), was known as "Confucius of Kansai", and later entered the dynasty as an official, and the official became a lieutenant. From Yang Zhen to his great-grandson Yang Biao, he served as a lieutenant, and later generations called his family the "Fourth And Third Duke".
In Yang Biao's generation, he gave birth to a son, known to everyone in the world, very famous, that is, Yang Xiu. Yang Xiu was the twelfth grandson of Yang Xi.
Yang Xiu was talented, literary, and quick-witted, but unfortunately he was killed by Cao Cao in the end.
When Cao Cao killed Yang Xiu, it was already in the Three Kingdoms period, and the Yang family was still a noble family, and many people in the clan served as officials in the court and played a very important role in the imperial court.
In the period of the Southern and Northern Dynasties, the Five Hu were chaotic, and the world was in chaos. In this chaotic world, the Yang family has produced another influential figure who has influenced the trend of history - Yang Jian, who is the founding emperor of the Sui Dynasty, and he is also the twentieth grandson of Yang Xi.
The Yang family really came to the peak because of this Yang Jian. The Sui Dynasty established by Yang Jian had a profound impact on Chinese history and played a very positive role in Chinese politics and culture.
For example, in terms of the political system, the sui dynasty's three-province and six-part system was used until the Qing Dynasty; in terms of the election system, the examination system used by the Qing Dynasty actually originated from the Sui Dynasty.
Historically, the Sui Dynasty only existed for more than thirty years, but its historical merits and contributions to the Chinese nation will always exist.
Yang Xi, who had been for hundreds of years, should not have thought that his descendants would one day be able to unify the whole country and create an imperial industry like Emperor Liu Bang.
